The C-Series

Two on the yard. More on the way.

The 107C and 77C side by side, same triple seed boxes, same penetrating coulter gangs, same red-and-gold iron. Pick the width that fits your tractor and your ground.

The Lineup

Three Widths. One Standard.

Every C-series drill runs the same three seed boxes and the same penetrating coulter system, so all three plant straight into heavy residue and hard ground. The only difference is working width: pick the one that fits your tractor and your acreage.

77C

2.13 m (7 ft)

The compact drill. Minimum 26 kW (35 HP), 17.8 cm (7 in) row spacing. Built for smaller tractors and tighter fields.

107C

3.05 m (10 ft)

The most popular drill on the market. The all-around workhorse.

147C

4.27 m (14 ft)

The widest in the line. Covers the most ground per pass for larger tractors and bigger acreages.

Seed Boxes

Three boxes on every model: main seed, small seed, and fertiliser or native grass. Plant complex mixes in one pass.

Built To Plant In Anything

Straight into the residue.

Disk openers slicing through stubble at depth

Penetrating Coulters

Cut, don’t push

Heavy-duty spring-loaded coulters slice straight through trash and packed ground instead of riding over it. Each gang carries enough down-pressure to hold depth in the hardest, driest no-till conditions.

Parallel-Linkage Depth Control

The same depth, every row

When the linkages sit parallel, every opener is carrying the same depth and the same pressure. Set it once with the depth spacers on the hydraulic cylinder and the whole drill drops to a repeatable seeding depth.

Parallel linkages keeping openers at uniform depth and pressure

Seed rate lever set along the GRAIN scale

Three Seed Boxes

Main seed, small seed, fertiliser

Slide the lever along the rate scale and the drill meters main seed, fine small seed, and fertiliser or native grass at the same time. Plant a complex cover or pasture mix in a single pass.
